Abstract: The FASTSUM Collaboration has calculated several quantities relevant for QCD
studies at non-zero temperature using the lattice technique. We report here our
results for the (i) interquark potential in charmonium; (ii) bottomonium
spectral functions; and (iii) electrical conductivity. All results were
obtained with 2+1 flavours of dynamical fermions on an anisotropic lattice
which allows greater resolution in the temporal direction.
